GAS=FIXTU RE.

SPECIFICATION forming part of Letters Patent No. 587,109, dated July 27, 1897.

Application filed June 5,1897- Serial No. 639,495. (No model.)

'such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to gas-fixtures; and the object thereof is to provide an improved gas cook or valve which is simple in construction and operation and which is designed to automatically prevent the escape of gas and which is also provided with means for indicating when the gas is turned on or off.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which Figure 1 is asectional, side View of our improved gas-fixture; Fig. 2, a section on the line 2 2 of Fig. 1; Fig. 3, a plan view of adetail of the construction; Fig. 4, a plan view of a plug which forms a part thereof, and Fig. 5 a cross-section of the plug on the line 5 5 of Fig. 4.

In the drawings forming part of this specification the separate parts of our improvement are designated by'the same numerals of reference in each of the views, and in the practice of our invention we provide a gas-fixture which comprises a cross-head 5, on which is formed a depending tubular portion 6, and the ends 7 of the cross-head 5 are so formed as to admit of the connection therewith of ordinary gas-pipes.

The cross-head 5 is provided with a small longitudinal bore 8 and with a transverse vertical bore 9, which communicates with the tnbular portion 6, as clearly shown in Fig. 1,

- and the lower end of the tubular-portion 6 is 15, through which the lugs or projections 11 are adapted to pass.

The conical transverse bore of the crosshead 5 is provided with a conical valve 16, which is provided with a shank 17, which passes downwardly through the tubular portion 6, and to the lower end of which is secured a head 18, which is provided at its upper end with a circular disk or plate 19, in the The downwardly-directed tubular portion 6 is provided near the upper end thereof with an inwardly-directed annular flange or shoulder 24, between which and the disk or plate 21 is mounted a spring 25, and the pins 22 pass loosely through corresponding openings formed in the plug 12, and in practice the plug 12 is passed upwardly into the enlarged lower end 10 of the downwardly-directed tubular portion 6 of the cross-head 5, the lugs or projections 11 passing through the notches or recesses 15, and said plug is then turned into the position shown in Fig. 2 and a pin or screw 26 is passed through the lower part of the enlarged portion 10 of said tubular portion 6 and into saidplug, so as to securely lock it in position. In this position of the parts the lower ends of the pins 22 bear on the disk or plate 9 and force the valve 16 downwardly, and in the normal position of said parts, or when the gas is turned off, the lower ends of said pins rest in the cavities or recesses 20, formed .in said disk or plate 19, and when it is desired to turn on the gas the valve 16 is turned by means of the head 18 of the shank 17, and in this operation the pins 20 and the disk or plate 21 are raised against the operation of the spring 25 and pass around over the top of the disk or plate 19, and when the gas is turned off this operationis reversed and the lower ends of said pins enter the notches or recesses 20 and produce a slight click or sound, which indicates that the gas is turned off, and it will be understood that the gas is never turned oif until the lower ends of said pins enter said notches or recesses.

This device is simple in construction and operation and is perfectly adapted to accomplish the result for which it is intended, and said device is also comparatively inexpensive.

Having fully described our invention, we claim as new and desire to secure by Letters Patent 1. A gas-fixture comprising a cross-head, having a longitudinal bore, and a vertical conical bore in which is mounted a conical valve the larger end of said valve being projected upwardly, said cross-head being also provided with a downwardly-directed tubular portion, said tubular portion being enlarged at its lower end, and provided with in wardly-direct'ed lugs or projections, and a plug which is adapted to be inserted thereinto, said plug being provided with an annular groove, and with transverse notches or recesses through which said lugs or projections pass, and said plug being also provided with an annular flange or rim at its lower end, and said valve being provided with a downwardlydirected shank which passes through said plug and is provided at its lower end with a head on which is formed. or to which is secured an annular disk or plate, and a disk or plate which is mounted on said shaft above said plug, and which is provided with pins which pass downwardly therethrough, and

which is adapted to enter cavities or recesses formed in the upper side of the disk or plate which is formed on or secured to said head, and a spring mounted on said shaft between the disk or plate with which said pins are connected, and a bearing formed in said tubular portion of said head, substantially as shown and described.

2. A gas-fixture, comprising a cross-head as 5, in which is formed a longitudinal bore, and a vertical transverse conical bore, in which is mounted a valve, the larger end of said valve being directed upwardly, said cross-head being provided with a downwardlydirectcd tubular extension as 6, which is enlarged at its lower end, and provided with inwardly-directed lugs or projections, and a plug as 12, which is adapted to be secured therein, said valve being provided with a downwardly directed shank which passes through said plug, and which is provided at its lower end with a head as 18, on which is formed a disk or plate as 19, and a disk or plate as 21, mounted on said shaft above said plug, and provided with pins as 22, which pass downwardly through said plug, and a spring as 25, mounted on said shaft, substantially as shown and described.

In testimony that we claim the foregoing as our invention we have signed our names, in presence of the subscribing witnesses, this 29th day of May, 1897.
